Working in Cumbernauld
We cover every part of Cumbernauld, including G67, and nearby Airdrie (5.6 miles) and Coatbridge (6 miles).
In Cumbernauld, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Cumbernauld house has a combi boiler, a loft shower can usually run on mains pressure without a pump. If your Cumbernauld home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options.
Water across much of Lanarkshire is soft. If that holds for your street in Cumbernauld, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
- A survey of the headroom across the room, with the usable height marked at each fitting position
- A check of the floor joists where a bath or large shower tray will sit
Decisions to make first
Getting the water pressure
A pumped shower suits a gravity system with a cold tank; an electric shower heats cold mains water at the point of use; a combi or unvented cylinder gives mains pressure throughout.
Roof window
A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.
Rules that apply in Scotland
In Scotland, forming a new bathroom in the loft or altering the drainage may need a building warrant. The Technical Handbook uses 15 litres per second extract for a bathroom, and water fittings are covered by the Scottish Water Byelaws 2014.
